Adjacent Generation

Substantial Generation — 6,132 MW total (Nuclear-dominant)
Criteria: Total operating generation capacity within 25-mile radius. Thresholds: ≤100 MW = No Generation/Data Gap • 100–500 MW = Limited Generation • >500 MW = Substantial Generation. Higher is better. Tier adjustments for intermittent-dominant (≥50% wind+solar) or retirement risk (≥25% retiring within 10 years).

Analysis

6,132 MW of operating generation within 25 miles, dominated by nuclear (Nuclear 44%, Solar 25%, Wind 12%, Gas 11%, Other 7%). Largest facilities include South Texas Project (1354 MW, Nuclear), South Texas Project (1354 MW, Nuclear), Old 300 Solar Center, LLC (430 MW, Solar). No announced retirements within ten years.

The site benefits from the nearby South Texas Project nuclear plant (2,709 MW combined across 2 units, 17.5 miles away), one of the largest nuclear facilities in the US. This baseload generation provides substantial grid stability for the local transmission system. The area also hosts significant solar development (1,540 MW across 8 facilities), driven by favorable irradiance conditions in coastal southeast Texas.

Gas-fired generation (674 MW from 5 qualifying units, primarily the Sweeny Cogen Facility) provides dispatchable capacity. 4 wind farms contribute 760 MW. Battery and storage facilities (450 MW from 8 units including the 300 MW GulfStar Power) indicate active grid modernization in the area.

Data vintage: EIA-860 2025 (early release). This is an early release; data has not been fully edited and may differ from the final annual publication.

Next Steps

  • Confirm ERCOT interconnection capacity at nearest substations given the high generation concentration
  • Evaluate transmission congestion risk due to high renewable penetration in the area
  • Assess potential curtailment risk for new solar/wind projects given existing renewable capacity
  • Verify South Texas Project long-term operating status and license renewal timeline
